GENERAL DESCRIPTION
The ADA4004-4 is a 1.8 nV/√Hz precision quad amplifier in a
16 mm2 LFCSP_VQ package featuring 40 μV offset, 0.7 μV/ºC
drift, 12 MHz bandwidth, and low 1.7 mA/amplifier supply
current.
The ADA4004-4 is designed on the high performance iPolar™
process, enabling improvements such as reduced noise and
power consumption, increased speed and stability, and a
smaller footprint size. Novel design techniques enable the
ADA4004-4 to achieve 1.8 nV/√Hz voltage noise density and
a low 6 Hz 1/f noise corner frequency while consuming just
1.7 mA/amplifier. The small package saves board space, reduces
cost, and improves layout flexibility.
Applications for these amplifiers include high precision controls,
PLL filters, high performance precision filters, medical and
analytical instrumentation, precision power supply controls,
ATE, and data acquisition systems.
The high performance ADA4004-4 is offered in the very small
16-lead, 4 mm × 4 mm LFCSP_VQ and the 14-lead, narrow
SOIC_N, lead-free, surface-mount packages. Operation is fully
specified from ±5 V to ±15 V from −40°C to +125°C.
